OE PATEBSON, NEW" JERSEY, A CORPORATION OF NEW FASTENER-INSERTING MACHINE.

Application filed August 26, 1924. SerialNo. 734,251.

This invention relates to fastener-insert ing machines. The accompanying drawings illustrate the invention as embodied in an eyeleting machine.

In the manufacture of certain articles of wearing apparel, leather goods and novel ties, it is, in some cases,desired to insert one or more eyelets, while in other cases it may be desired merely to punch one or more holes without setting any eyelet. Even in the first case itis necessary to punch holes to receive theeyelets. In dealing with such articles and others in which holes are to be punched singly with or without setting eyelets it is not feasible to use eyeleting machines that include automatic punching mechanism and automatic work-feeding mechanism, since machines of that type are too large and costly and are designed to operate at high speed on work that requires a series of eyelets uniformly spaced one from another. Consequently, the manufacturers of articles of the character above mentioned have heretofore been supplied with simple and comparatively inexpensive punching machines and with separate machines having eyelet-setting mechanism but no punching mechanism or work-feeding mechanism. While this equipment of two separate machines, one for punching holes and the other for setting eyelets, requires only a relatively small investment as compared to the cost of an automatic punching and eyeleting machine,'it has certain disadvantages, the elimination of which is one of the objects of the present invention.

Stated more definitely, an object of the invention is to provide an improved eyeleting machine of the simple type above referred to which may be quickly and readily converted into a machine for performing punching operations only and be just as readily when desired reconverted intofan eyeleting machine. To this end, and in accordance with the present invention, the illustrated eyeleting machine, which is of a well-known foot power type, in which eyelets are supplied automatically by a raceway to one of the setting tools which is provided with a spring-pressed spindle normally projecting to pick the leading eyelet from the raceway and hold it for insertion in the work, is provided with a member, illustrated as a cap or thimble, formed to be carrying setting tbol referred to.

seated on the eyeleteettingtool to serve as a punch bed when the machine is to be used for punching operations only, together with means for maintaining the punch-bed in that position with sufficient force to keep the spr1ng-pressed spindle repressed so that cannot function. The illustrated cap or thimbleis adapted to be attached and detached at will and besides serving as a punch-bed, when attached has the further advantage just indi'catedof preventing the spindle from picking eyelets from, the'ra'cein a punch-bed having one or more resilient elements integral therewith and arranged to hold the punch-bed in operative position on a fastener-inserting tool without requiring the use of any tool to attach or detach it.

Although the invention is herein set forth with particular reference to eyeleting mainvention consists chines of a well-known type, since it was in view of problems which, as above explained, have arisen in the use of such machines that the invention was developed, it should be understood that in various aspects the invention is not restricted in its applicability to fastener-inserting machines of theillustrated type. v

Referring to the drawings,

Fig. 1 is a vertical section of a portion of a well-known type of fastener-inserting machine converted into a punching machine by devices hereinafter described, and

Fig. 2 is a vertical section on a larger scale showing the punching devices in the act of punching a hole in an article of work.

So far as the fastener-inserting mechaisthe sameas that more fully shown and described in Letters Patent of the Unitedv States No. 898,729, granted September 15,

nism is illustrated herein the construction 1908,. on application of John F Davey. To e facilitate a description of the operation of the punching devices a brief preliminary description will be directed to the fastenerinserting mechanism per se.

The illustrated machine comprises a frame 10 designed to stand on a bench 12. A stationary overhanging portion 14 of the frame is bored to receive the shank 16 of a tool for clenching the fasteners, while the lower portion of the frame is bored to provide a bearing 18 for a vertically movable of the raceway will present .the leading fastener to the fastener-inserting tool 22 while the latter is rising, and then be re tracted to the left to avoid interfering with the inserting tool.

The operating mechanism is designed to be operated by a treadle (not shown) and includes a rod 30 by which the motion of the treadle is transmitted. The rod 30 is normally maintained in its upper position by a spring 32. The lower portion of the frame 10 supports the fulcrum'pins 84 and 36. A lever 38 mounted on the pin 34 is connected to the treadle rod by a pivot pin 40. Toggle members 42' and 44 are connected respectively to the lever 38 and to the plunger 20 by pivot pins 46 and 48 and are connected to each other by a pivot pin 50. The pin 50 also extends through an arm 52 whose function is to guide the knee of the toggle as formed by the connection between the links 42 and 44. The arm 52 is mounted to swing on the pin 36. This train of connections furnishes all that is necessary to operate the plunger 20, but otherelements are included to operate the raceway.

. To utilize the toggle member 44 forthe purpose of reciprocating the raceway said toggle member is formed with an arm 54 the upper end of which carries an anti-fricconstructions for operating in this manner,

the spindle 64 is normally projected above.

the usual clenching tool, I prefer to provide a combined punching and clenching tool to avoid substituting one tool for. another whenever it is desired to convert the machine from a fastener-inserting machine into a punching machine and vice versa. In accordance with this preference, the illustrated construction includes a tool or anvil having an annular clenching surface 68 and a punching portion 70 projecting therefrom, said portion being tubular and its bore 72 having an outlet at one sideto discharge the disks or chips punched from the work. The fastener-inserting tool 22 and the combined punch andset 70, 68 are arranged in con fronting relation to each other so that they may cooperate to punch holes or insert fasteners, as the case may be. When used to insert fasteners, the punching portion 70 enters the fastener and guides it to the clenching surface 68, and inthat capacity it is sometimes termed a pilot. i

As shown best in Fig. 2, a punch-bed is provided by a plate 74 and this plate is seated on the upper end of the inserting tool 22. In this position the punch-bed engages the spindle '64 and depresses, it into the tool 22 so that it is prevented from engaging the leading eyelet at the delivery end of the raceway. Thus, the mer'eprcscn'ce of the punch-bed in its cooperative relation to the inserting tool accomplishes all that is necessary to prevent the machine from functioning as a fastener-inserting machine even though the raceway, charged with fasteners, continues to movev to and from its regular fastener-presenting position. The punch-bed is preferably the crown portion of a cap or thimble 76of hardened steelor other suitable metal, and said cap or thimble is formed to fit over the inserting tool so that it may be readily slipped on and removed. The sleeve portion of the thimble is preferably formed with kerfs 77 by which it is provided with resilient spring tongues 78 adapted to grip the sides of the tool 22 with suflicient force to maintain the punch-bed seated upon the upper end of the tool notwithstanding the tendency of the spring 66 to separate it from its seat. N0 tool isrequired to attacli or detach the member76, since the force of the spring 66 is so slight. that the gripping action of the spring tongues 78 may easily be powerful enough to hold the spindle in its fully depressed position without making it difficult to attach and detach the member 7 6 with the bare hand. That port'ion of the sleeve in which the kerfs are formed to provide the tongues 78, is preferably thin for the sake ,of resilience,

whereas the upper portion of the sleeve is relatively thick to provide an external shoulder 7 9 by which to detach the thimble from the tool 22. Moreover, as shown, the

chine or as a simple punching machine according to whether themember 76'is detached or attached. When attached it functions first to prevnt cooperation of the spindle 64 and the raceway and thereafter functions to force an article of work 80 against the punching element as shown.
